I'm off again to SIN and considering where to spend three days. The past few times I've done Phuket, Bangkok, and Kuala Lumpur. I had thought about Hong Kong, but the preferred hotel is sold out of awards. I wanted to go somewhere new and thought Hanoi would be an interesting choice (I have a coworker who is Vietnamese born and thought that a gift back would be a great surprise). Is three days enough? How are traveling conditions over there? I'd likely be staying at the Hilton Hanoi.
